arm, imx6: add alternative PAD_CTL_DSE constants
Not all i.MX6 pads use the same drive strength table. So far only the
240 Ohm to 34 Ohm table was available. Because the constants used have
speaking names it can be confusing to use e.g. PAD_CTL_DSE_48ohm when
according to the reference manual 52 Ohm is the correct value. This
patch adds the 260 Ohm to 37 Ohm table.
For example, the IOMUXC_SW_PAD_CTL_PAD_SD2_CLK register (SD-card clock)

same timing. The changes are:
- Disable ODT on read (JEDEC standard JESD79-3F says in chapter
5.2.3 ODT during Reads: "As the DDR3 SDRAM can not terminate
and drive at the same time, RTT must be disabled at least half
a clock cycle..." and also MX7D SABRESD is disabling it)
This alone fixed memory issues for two Colibri iMX7 1GB modules
which showed issues before
- Make sure tRFC(min) is at least 260ns
- Make sure tRC is >50.625ns

The intended usage is for the full U-Boot stage to evaluate this in
scripts and then adapt its boot-order when using distro-boot.

spl: document 'chosen/u-boot, spl-boot-device'
To let the full U-Boot know where it was booted from (i.e. which of
the entries in /chosen/u-boot,spl-boot-order' contained a valid
image), we define (and document) /chosen/u-boot,spl-boot-device as the
property that could/should automatically be injected by SPL.
This commit only contains a documentation change, which documents the
new property and the intended usage.
